Dragonflies are an ancient insect that dates back 320 million years. It is an important class of insects that benefit humans. We often hear the phrase "dragonflies dot water", which is actually the biological characteristic of dragonflies laying their eggs in water.
By imitating the unique structure of the dragonfly compound eye, people have created bionic cameras that can take thousands of duplicate photos at a time. The study of the flight mechanism of dragonflies is of great significance to the design and manufacture of aircraft. Dragonflies can also be used to monitor environmental pollution, and have medicinal, edible and ornamental value.
Today we will share the paper-cutting method of dragonflies, and the pattern after cutting is shown in the following figure. These five dragonflies are cut out at one time using the paper-cutting technique of tuanhua.
Let's share the specific steps of dragonfly paper cutting.
1. Take a square piece of red paper and fold it in half along the diagonal into a triangle.
2. Divide the bottom edge of the triangle into 180 degrees at an average angle of 180 degrees, and divide it into five parts, each part is 36 degrees.
3. Fold the right corner of the triangle to the left and coincide with the corresponding edges of the four places, see the figure below.
4. Fold the new triangle in half along the midline and fold it again, see the figure below.
5. Fold the remaining fifth of the left corner backwards and overlap with the rightmost line. This is the ten-fold method, also known as the five-fold method.
If you don't have a protractor at hand and don't know how to determine 36 degrees, then it is better to say that you fold the left and right corners in half along the center of the bottom edge, and constantly adjust the angle until the two outer edges and the other side's creases are aligned separately.
The shape of the back after fully folded is as follows
6. After folding, draw the following dragonfly pattern. Wings, antennae, and circular arcs used to connect to each other.
7, along the drawing of the pattern cut off, in the dragonfly and then draw three crescent patterns, as a decorative line, these three crescent patterns can also be in the previous step of a one-time all finished, after the painting is as follows.
8, cut off these three crescents, at this point, the entire pattern is all cut.
9. Unfold the cut colored paper, a total of five dragonflies surround the same flower, forming a peaceful picture of dragonflies playing.
The above is today's dragonfly paper-cutting sharing, the difficulty is not large, there is no cutting method, the pattern is also easy to draw, the clippers can do it themselves, cut out the beautiful dragonfly pattern.
